Burger chain Shake Shack orders up IPO

Shake Shack is bringing its burgers, milkshakes and crinkle-cut fries to Wall Street.

The burger chain filed for an initial public offering Monday, hoping to raise as much as $100 million. It didn't say how many shares it plans to offer, or at what price, so that number may change. It plans to use the cash raised to open more restaurants, including its first one in Austin, and to renovate existing stores.

The origins of the restaurant date back to 2001 when Union Square Hospitality Group, a company owned by restaurateur Danny Meyer, opened a hot dog cart in Manhattan's Madison Square Park. Three years later, a more permanent kiosk opened in the same park. There are now 63 Shake Shack restaurants around the world. In 2013, the company had revenue of $84.5 million, up 45 per cent from the year before. It posted a profit of $5.4 million in 2013, up 31 per cent from 2012.

Shake Shack cooks its burgers to order and promotes its use of natural ingredients, including hormone- and antibiotic-free beef. It's known for its long lines and its vibrating pagers that signal when an order is ready.

Other fast-casual restaurant operators have fared well after their IPOs. Shares of chicken chain El Pollo Loco Holdings Inc. have risen about 40 per cent since its July IPO, while shares of Mediterranean-style chain Zoe's Kitchen Inc have doubled since its April IPO.

Shake Shack Inc. plans to list its stock on the New York Stock Exchange under the ticker symbol 'SHAK'.
